The specific embodiment
Fig. 1 and 2 is the schematic diagram that is designed for the driving belt assembly 20 of elevator system.Many ropes 22 are arranged essentially parallel to the longitudinal axis arrangement of driving belt assembly 20.In one example, rope 22 is made by hawser.
These grooves are produced by some manufacturing steps, and many steps wherein are widely known by the people in the art, and it is suitable for forming driving belt assembly 20.In the embodiment of Fig. 1 and 2, groove spacing distance difference makes spacing difference between the different grooves.For example, first interval 44 separates the grooves 32 of groove 30 with vicinity.A different spacing 46 separates the groove 34 of groove 32 with vicinity.Similarly, spacing 48,50,52 is different with 54 size.
It is all different to there is no need the interval shown in all, still, preferably should provide different spacings as much as possible along the length direction of this driving belt assembly.As a kind of method of practicality, the repeat pattern of different spacing generally will extend along the whole length of driving belt assembly 20.According to driving belt assembly and the details that is used to form and uses the equipment of jacket 24, the pattern of different spacing will repeat with different spacing distances.The spacing distance that pattern repeats preferably should be big as much as possible in the scope of making the equipment permission.In one example, a kind of pattern of different spacing is arranged, its about per two meters are repeated once.In each two meters section, select spacing between the adjacent grooves different and be acyclic.
By changing the spacing between the adjacent grooves, when elevator system is worked, contact with other elevator system element (as sheave) and the noise composition that causes is distributed in the wideer frequency range by the driving belt assembly.Therefore, avoided the noise of steady frequency, it has eliminated the possibility that produces audible, disagreeable audible sound.
Except changing the spacing between the groove, the layout of invention provides the ability of the length of change rope " section ", and rope " section " produces (but needn't be included in the layout of invention) by some manufacture method.Driving belt assembly according to the present invention's design can comprise a series of cord segment, and the distance between rope and the jacket outer surface changes along these cord segment.The end of this rope " section " overlaps with the position of groove.The spacing that changes groove has also just changed the length of cord segment, has therefore changed the geometry of rope with respect to the jacket outer surface.By the layout of invention, the length of cord segment changes along the length direction of driving belt.
Because these cord segment have different length, therefore there is not the geometric mode cycle, that repeat of rope with respect to the jacket outer surface.By changing the length (promptly changing with respect to the spacing between the similar distortion in the rope position of jacket outer surface) of cord segment, the noise or the vibration that are caused by the physical dimension of rope are reduced or have eliminated.
The periodic characteristic of the physical dimension by eliminating rope the invention provides the remarkable advantage that is used to reduce vibration and noise and produces when elevator system is worked.
